Abstract: In the history of modern Chinese literature and art,the revolutionary Literature and Art Popularization Movement led by the Communist Party of China steadily advanced through popular cultural fields.The representational practices,which are epitomized by Xingguo Folk Songs,of literary and artistic popularization in the Chinese Soviet Regions demonstrated three functional values (entertainment,mobilization,and pedagogy) and highlighted three theoretical qualities:people-centered nature,national character,and revolutionary essence.Yan'an literature and art comprehensively inherited the experiences of the literature and art in Chinese Soviet Regions,taking Yan'an Yangge as a pivotal vehicle to reform and innovate.Through the integration of intellectual elite and the worker-peasant masses,it established the developmental trajectory of people's literature and art,strengthened CPC's Mass Line,and further demonstrated its historical impetus to China's modern revolution.Reexamining the representational practice logic from Xingguo Folk Songs to Yan'an Yangge through the lens of popular cultural fields not only contributes to restoring and revealing the early formation of people's literature and art,but also facilitates a deeper understanding of the popularization of revolutionary literature and art.

Key words: people's literature and art, popular cultural fields, Xingguo Folk Songs, Yan'an Yangge, the Mass Line
